Diagnosis. Distinguished from L. tuberculatum by the humeri strongly projecting beyond lateral margins of hemelytra and looking like horns curved forward. Pronotal transverse carinae often obsolete and masked by incrustation. Ventro-apical margin of pygophore with oblique, convex lateral parts ( Fig. 14). Ventral infolding of rim of pygophore very narrow and slightly elevated ( Figs 19, 20). Parandria rounded; their outer half sclerotized, crescent-shaped, inner half almost membranous, without notch. Outer walls of lateral branches of ventro-lateral lobes of conjunctiva more broadly rounded than in other species of this group ( Fig. 24). Female genitalia. Caudal margins of first gonocoxae almost straight. Medial part of spermathecal duct extending beyond middle or anterior margin of abdominal sternum IV ( Fig. 30).

Measurements (mm) and ratios. Total length 5.25–6.40, width of pronotum 3.30–4.25, width of abdomen 3.25–3.95, ratio head length/head width 0.98–1.00, ratio scutellum width/scutellum length 0.50–0.53. Length of antennal segments I–V: 11–13: 17–21: 11–12: 10–12: 23–26.

Etymology. This species is named to denote very narrow ventral infolding of rim of pygophore.

Distribution. Kazakhstan, Turkmenistan, Uzbekistan, Tajikistan, mainly in foothills.
